ABSTRACT:
The invention provides a sheet metal joint and a method for forming a sheet metal joint. The sheet metal joint includes first and second metal sheets disposed in a parallel relation to one another. Each of the first and second metal sheets has a plurality of perforations with a tang extending from each perforation. The tangs of the second sheet and the tangs of the second metal sheet are curled together in opposite rotational directions. The tangs of the first metal sheet space the first and second metal sheets from one another and the tangs of the second metal sheet substantially fixedly engage the first and second metal sheets with respect to one another.
